Mission
The State Route 4 Bypass Authority (SR4BA or Authority) is a Joint Exercise of Powers agency charged with delivering the State Route 4 Bypass Project (Bypass) in eastern Contra Costa County. Caltrans adopted the Bypass as the new State Route 4 in 2012 and relinquished the portion of the old State Route 4 located in the downtown areas of the cities of Oakley and Brentwood and a portion of Contra Costa County. The Authority’s jurisdiction encompasses the eastern portion of the County, including unincorporated areas as well as the Cities of Antioch, Brentwood, and Oakley.
